STOCK-WATERING THOUGH.

Specification of Letters Patent.

Patented March 19, 1907.

Application tiled March 12.1906. Serial No. 305,552.

To ati/ whom t may cori/cern,.-

Be it known that I, BENJAMIN F. BOOTH, a e citizen of the United States, residing at Indianola, in the county of Warren and State of Iowa, have invented a certain new and useful Stock-Watering Trough, of which the following is a specification.

'Ihe object of my inventionis to provide a stock-watering trough of simple, durable, and inexpensive construction of the class in which the water is automatically maintained. l at a predetermined level in the trough.

My invention consists in the construction, arrangement, and combination of the parts i of the automatic controlling-valve whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows a sectional view of a stockwatering trough connected to the supplyl tank and provided with my improved regulating-valve device. Fig. 2 shows an enlarged sectional view of the valve device detached. The dotted lines illustrate the position of the valve and working partswhen open. Fig. 3 shows an edge view of the float. j

Fig. 4 shows an inside face view of the valvecontrolling arm and the spring for aiding in holding the valve in a closed position, and Fig. 5 shows a detail sectional view illustrating the, valve closed valve-seat.

Referring to the accompanying drawings, I have used the reference-numeral to indicate the stock-watering trough.

11 indicates a cylindrical valve-chamber having at one end a flange 12 to be connected by screws 13 with the inner face of the stockwatering trough. On the other end of the valve-casing is a flange 14, at the upper end of which are two projections 15, formed with tightly against the and near the lower end of the flange 14 are the brackets 17 to receive the rock-shaft 18. Formed on the inner end of the valve-chamber is an annular shoulder 19, upon which is seated a cylindrical valve-seat 20, preferably made of rubber or other flexible material. Its outer end stands spaced apart from the interior of the valve-chamber, so that when a cylindrical valve is forced against said outer end the material of the valve-seat may expand and be forced outwardly, as shown in Fig. 5, to thereby form a tight-fitting seat for the valve. Fixed to the rock-shaft 18 is an the board is a metal valve-rod 21.

, this purpose.

upwardly-projecting valve-arm 21, which is normally held inwardly away from the plate 14 by means of the spring 22, which has coils l in its end portions surrounding the rockshaft 18 and a loop 23 at its central portion engaging the arm 21. The ends of the spring are secured at 24 to the plate 14. The valve is indicated by the numeral 25, and is of cylindrical form and provided with a valvestem 26, pivoted to the valve-arm. The float for controlling the valve-arm preferably comprises a board 27 with a central opening 28 near one end. On the under surface of plate 29, having 'an opening 30 in line with the opening 28 and designed to receive the upper end of the I pivotally and adjustably connect the float 27 with the lugs 15 by means of two screw-threaded rods 31, screwed into the ends of ing right-angled extensions 32 on their ends which are passed through the slots 16of the lugs 15.

In practice I so arrange the iloat relative to the lugs that when the float is in an approximately horizontal position it will hold the valve-rod 21 in such position that the valve will be tightly fitted against the valve-seat 20. The spring 22 serves to aid in holding the valve to its seat. float 27 descends by gravity, it will permit the arm 21 to move toward the plate 14, as shown by dotted lines in Fig. 2, whereupon the valve 25 will be removed from its seat and water permitted to enter the tank .10 until the iloat is raised by the water and by the aid of the spring. If it is desired to adjust the float so that the valve will be seated more or less firmly when the float is in a horizontal position, this may be done bysimply turning the screws 31, and none of the parts under water need be touched by the operator for Furthermore, the entire iloat may be very readily and quickly removed by turning the ends 32 of the screws 31 to an upright position and then elevating the loat to a substantially vertical position and withdrawing the ends 32 .through the slots 16 but so long as the ends 32 are in a horizontal position the float cannot be removed or accidentally displaced.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is-

l. A stock-watering trough, comprising a trough-body, a valve-seat connected therethe lloat 27 andhav- When the IOS with, a valve to close against the seat, a valvestem connected therewith and projected into the tanl -body, a roch-shaft pivotally supported within the tank-body below the valve, an arm ixed to said rock-shaft and projected upwardly and inwardly, said arm having the valve/*stein pivoted thereto, a spring having its ends coiled upon the rock-shaft and attached to the tank-body and formed with a loop at its central portion to engage said arm and normally hold it inwardly with the valve closed against its seat and a loat pivoted above the valve and in engagement with said arm designed when lowered to iiorce the arm outwardly as required to open the valve.

2. A stock-watering trough comprising a trough-body, a cylindrical valve-chamber Formed with an annular shoulder near one end, a cylindrical 'Iiexible valve-seat mounted. in said shoulder and spaced apart at its outer end from the interior or' the valve-chamber, a valve in the chamber, a valve-stem connected therewith and projected inwardly, a flange at the outer end oli the valve-chamber to be attached to the trough, a flange at the inner end oi the valve-chamber `formed with slotted l lugs at its top, a rook-shaft mounted on the inner lace oi the inner [lange near its bottom, a valve-arm iixed to the rock-shaft and projected upwardly and inwardly, a spring hav ing coils on its ends and a loop at its central l portion, said coils wound around the shaft l, and said loop engaging the valve-arm to j yieldingly hold the valve-arm inwardly, said j valve-stem also connected to the valve-arm, j a iloat to engage the u per end of the valvearm, two screw-threac ed rods having rightangled projections, seated in the outer end of the iloat with said right-angled projections j passed through the slotted lugs to pivotally, adjustably and detaehably connect the Iloat to the inner i'lange.

3. A stock-watering trough comprising a trough-body, a cylindrical valve-chaniher formed with an annular shoulder near 'one end, a cylindrical vflexible valve-seat inounted in said shoulder and spaced apart at its outer end from the interior ot the val ve-ch ai n ber, a valve in the chamber, a valve-stein connected therewith and projected inwaixlly, a ilange at the outer end or" the 'alvearhalnber to be attached to the trough, a v[lange at the inner end. of' the valve-chamber formed with slotted lugs at its top, a rock-shaft mounted on the inner Jface olIV the inner llange n near its bottom, a valve-arm lined to the rock-shaft and projected upwardly and inwardly, a spring having coils on its ends and a loop at its central portion, said coils wound l around the shaft and said loop engaging the valve-arm to yieldingly hold the valve-arm inwardly, said valve-stem also connected to the valve-arm, a iloat Vorn'ied with an opening near its outer end and with a nictal plate at the under surface of the opening, said plate iormed with an opening` to receive the upper end. of the Talve-arnn two screwthreaded rods having right-angled projccn tions, seated in the outer end ol the float with said right-angled projections passed through the slotted lugs to pivotally, adjustahly and detachably connect the iloat to the inner `flange.
